Question

Which of the following is true for gas phase reactions?

(a) Increase in moles of product increases the volume of the reaction mixture

(b) Increase in moles of product decreases the volume of the reaction mixture

(c) Decrease in moles of product increases the volume of the reaction mixture

(d) Increase in moles of product does not affect the volume of the reaction mixture

I got this question in an internship interview.

Query is from Liquid and Gas Phase Reactions topic in division Kinetics of Homogeneous Reactions of Chemical Reaction Engineering

Answer 1

The correct choice is (a) Increase in moles of product increases the volume of the reaction mixture

The best I can explain: Increase in moles of product increases reaction mixture volume. For a reaction proceeding such that the moles of products are higher than moles of reactants, volume of reaction mixture increases.
